"I don't have help. No one else runs my social media," she tells The Hollywood Reporter.

1. Don't Be Too Calculated

I don't plan it out. If I'm feeling good about myself, and I like my outfit or hair and makeup or contouring, I will share it. Or if I have pictures I just got back from a photo shoot, I'll share a series. I love a good throwback. There's so much you can share, but I don't have a method to it.

2. Master Your Own Domain

I don't have help. No one else runs my social media. It's whatever I feel like posting. From collages and screen grabs and cropping, it's a whole process, and I do it. I also don't do filters. I can't ever figure it out, and I don't like the way they look, so I'd rather not bother.

Being a big sister, I want to know what's going on in [my sisters'] lives. I can look on Instagram and be comforted in knowing where Kendall is. My stepdad [Bruce Jenner] has a secret account. He told me that he set it up so he can see what my sisters are doing, too.

4. Post Pictures, Not Quotes

I don't follow [other celebs] just because we're friendly. I only like what inspires me. I don't like it when people post quotes all the time. I follow accounts of people I don't know, but I'm inspired by their fashion choices, like The Curvy Fashionista [@mariedenee].

I try really hard not to promote products — or very rarely. I was obsessed with these waist shapers after I had a baby, so I would put those up. I took a picture with an eyelash product I like. Some people post a couple times a day to promote their products, but I won't.
